Correct Answer: Option D

Atolls, fringing reefs, and barrier reefs are all distinct types of coral reefs.

They are classified based on their structure, formation, and proximity to landmasses.

Atolls are typically circular reefs surrounding a lagoon.

Fringing reefs grow close to the shoreline.

Barrier reefs are separated from the mainland by a lagoon.

Therefore, the correct answer is that all three (Atoll, Fringing Reef, and Barrier Reef) are types of coral reefs.
